OBJECTIVE: We tested the hypothesis that physically active people with spinal cord injury do not have increased subclinical atherosclerosis compared with an age-matched able-bodied group. METHODS: Subjects comprised 28 wheelchair athletes with spinal cord injury (mean age 22 (standard deviation (SD) 3) years) and 24 recreationally active aged-matched able-bodied control participants (mean age 23 (SD 3) years). Intima media thickness, arterial compliance and beta stiffness of the common carotid artery were measured using B-mode ultrasound. Aortic augmentation index was derived from applanation tonometry of the radial artery. RESULTS: Carotid mean intima media thickness in persons with spinal cord injury did not differ from that of controls (0.46, SD 0.07 vs 0.44, SD 0.06, p=0.94). Carotid artery beta stiffness in persons with spinal cord injury also did not differ from that of controls (4.92, SD 1.6 vs 5.70, SD 1.6, p=0.08). The augmentation index did not differ between groups (4.0% [-3.8-12.3] vs 4.5 %, [-8.0-12.0] of median and interquartile range, p=0.78). CONCLUSION: Participation in regular exercise may preserve arterial function in individuals with spinal cord injury when compared with aged-matched able-bodied participants.
